Do you get enough speed with FW800?
I think you need at least esata.
The drobo is rubbish!
You need a reliable raid, at least Raid5, better Raid6 raid. You can also visit our forum “Raids and array systems”.
The lowest step I would take is a sonnet RQ400 with 4x4TB enterprise class harddiscs.
The sonnet is pretty reliable, has FW800 and esata connections. The new sonnet is the R400S which has just esata connections. For your mac you need a good 4xEsata PCIX card (Slotx4). You can operate up to 4 esata arrays. The speed with esata is around 200 MB/s. Speed is going down when you fill up the array. Don’t go over 80% of the arrays capacity. The speed will go down dramatically. That is the bad thing bout esata. The next step would be miniSAS – very good, reliable and Raid6 possibility (two drives can fail) There is the Sonnet R800. It comes together with the PCIX card. It is a 8bay raid system. We run this array for years now. There are also other brands on the market f.e. Proavio with the same specs.
One thing about arrays is: A Raid is just there to work, work, work. You don’t realize that it’s there.
Don’t go for a cheap system like drobo. Buy a decent product. Very important are the Harddrives within such an array. They must all be the same size, brand and type. Just go for enterprise class only! We deal with this for years, have tried a lot and ended with Hitachi Ultrastars only!
